How to retrieve a file from a server via SFTP?

Question

I'm trying to retrieve a file from a server using SFTP (as opposed to FTPS) using Java. How can I do this?

Another option is to consider looking at the JSch library. JSch seems to be the preferred library for a few large open source projects, including Eclipse, Ant and Apache Commons HttpClient, amongst others.

It supports both user/pass and certificate-based logins nicely, as well as all a whole host of other yummy SSH2 features.

Here's a simple remote file retrieve over SFTP. Error handling is left as an exercise for the reader :-)

JSch jsch = new JSch();

String knownHostsFilename = "/home/username/.ssh/known_hosts";
jsch.setKnownHosts( knownHostsFilename );

Session session = jsch.getSession( "remote-username", "remote-host" );    
{
  // "interactive" version
  // can selectively update specified known_hosts file 
  // need to implement UserInfo interface
  // MyUserInfo is a swing implementation provided in 
  //  examples/Sftp.java in the JSch dist
  UserInfo ui = new MyUserInfo();
  session.setUserInfo(ui);

  // OR non-interactive version. Relies in host key being in known-hosts file
  session.setPassword( "remote-password" );
}

session.connect();

Channel channel = session.openChannel( "sftp" );
channel.connect();

ChannelSftp sftpChannel = (ChannelSftp) channel;

sftpChannel.get("remote-file", "local-file" );
// OR
InputStream in = sftpChannel.get( "remote-file" );
  // process inputstream as needed

sftpChannel.exit();
session.disconnect();

Cheekysoft, I noticed - while using Jsch - removing files on the sftp-server does not work. Also renaming files does not work too. Any ideas please??? Andy – Jan 31 '11 at 01:24

What is that code block after the assignment of session? Is that some fancy Java syntax I've never seen? If so - what does it accomplish being written that way? – Michael Peterson Oct 17 '14 at 14:19

@p1x3l5 standard java syntax allows a block to be inserted anywhere; it can be used to provide finer control over variable scope, if you wish. However, in this case, it is just a visual aid to help indicate the two implementation choices: either use the interactive version which requests a password from the user, or use a hardcoded password requiring no user intervention but arguably an additional security risk. – Cheekysoft Nov 05 '14 at 10:37
Another example relying on JSch library : https://www.baeldung.com/java-file-sftp – Raymond Chenon Oct 20 '21 at 16:30

@RaymondChenon Be aware that this example on Baeldung does not appear to close the session after the transfer which could cause issues on the server side. You would probably want to call `channelSftp.getSession().disconnect()` after `channelSftp.exit()`. – Robert Hunt Aug 12 '22 at 08:07

Here is the complete source code of an example using JSch without having to worry about the ssh key checking.

import com.jcraft.jsch.*;

public class TestJSch {
    public static void main(String args[]) {
        JSch jsch = new JSch();
        Session session = null;
        try {
            session = jsch.getSession("username", "127.0.0.1", 22);
            session.setConfig("StrictHostKeyChecking", "no");
            session.setPassword("password");
            session.connect();

            Channel channel = session.openChannel("sftp");
            channel.connect();
            ChannelSftp sftpChannel = (ChannelSftp) channel;
            sftpChannel.get("remotefile.txt", "localfile.txt");
            sftpChannel.exit();
            session.disconnect();
        } catch (JSchException e) {
            e.printStackTrace();  
        } catch (SftpException e) {
            e.printStackTrace();
        }
    }

A `finally` block should be used to include the channel clean-up code, to ensure that it always runs. – hotshot309 Nov 18 '13 at 17:47
I'm getting this exception now: ```com.jcraft.jsch.JSchException: Session.connect: java.security.InvalidAlgorithmParameterException: Prime size must be multiple of 64, and can only range from 512 to 2048 (inclusive)``` – fIwJlxSzApHEZIl Jan 19 '16 at 19:07
I found JSCH to have 0 or 1 extra dependencies. You can ignore the JZLIB dependency if you disable compression. // disable compression session.setConfig("compression.s2c", "none"); session.setConfig("compression.c2s", "none"); – englebart Feb 01 '19 at 19:19

Below is an example using Apache Common VFS:

FileSystemOptions fsOptions = new FileSystemOptions();
SftpFileSystemConfigBuilder.getInstance().setStrictHostKeyChecking(fsOptions, "no");
FileSystemManager fsManager = VFS.getManager();
String uri = "sftp://user:password@host:port/absolute-path";
FileObject fo = fsManager.resolveFile(uri, fsOptions);

Another nice thing to do is to set the timeout, so that if the remote system is offline, you don't hang there forever. You can do this just like was done for the host key check disable: SftpFileSystemConfigBuilder.getInstance().setTimeout(fsOptions, 5000); – Scott Jones Sep 06 '12 at 13:35

A nice abstraction on top of Jsch is Apache commons-vfs which offers a virtual filesystem API that makes accessing and writing SFTP files almost transparent. Worked well for us.

is it possible to use pre-shared keys in combination with commons-vfs? – Benedikt Waldvogel May 15 '09 at 13:46

Yes it is. If you need non-standard identities you can call SftpFileSystemConfigBuilder.getInstance().setIdentities(...). – Russ Hayward Jan 27 '11 at 11:05
You can use pre-shared keys. But this keys have to be without password. OtrosLogViewer is using SSH key authorization with VFS but requires to remove passphrase from key (http://code.google.com/p/otroslogviewer/wiki/SftpAuthPubKey) – KrzyH Dec 18 '12 at 13:05
I must say, that library is reallt overhead for the question requirements. the part that handles sftp is something like 10% of the library or even less... – Itay wazana Jun 02 '21 at 09:42

This was the solution I came up with http://sourceforge.net/projects/sshtools/ (most error handling omitted for clarity). This is an excerpt from my blog

SshClient ssh = new SshClient();
ssh.connect(host, port);
//Authenticate
PasswordAuthenticationClient passwordAuthenticationClient = new PasswordAuthenticationClient();
passwordAuthenticationClient.setUsername(userName);
passwordAuthenticationClient.setPassword(password);
int result = ssh.authenticate(passwordAuthenticationClient);
if(result != AuthenticationProtocolState.COMPLETE){
     throw new SFTPException("Login to " + host + ":" + port + " " + userName + "/" + password + " failed");
}
//Open the SFTP channel
SftpClient client = ssh.openSftpClient();
//Send the file
client.put(filePath);
//disconnect
client.quit();
ssh.disconnect();

I agree (belatedly), it worked fine for the original site/download I required but it refuesed to work for the new one. I'm in the process of switching to JSch — David Hayes, Jan 27 '11 at 14:09

There is a nice comparison of the 3 mature Java libraries for SFTP: Commons VFS, SSHJ and JSch

To sum up SSHJ has the clearest API and it's the best out of them if you don't need other storages support provided by Commons VFS.

Here is edited SSHJ example from github:

final SSHClient ssh = new SSHClient();
ssh.loadKnownHosts(); // or, to skip host verification: ssh.addHostKeyVerifier(new PromiscuousVerifier())
ssh.connect("localhost");
try {
    ssh.authPassword("user", "password"); // or ssh.authPublickey(System.getProperty("user.name"))
    final SFTPClient sftp = ssh.newSFTPClient();
    try {
        sftp.get("test_file", "/tmp/test.tmp");
    } finally {
        sftp.close();
    }
} finally {
    ssh.disconnect();
}

            Channel channel = session.openChannel("sftp");
            channel.connect();
            ChannelSftp sftpChannel = (ChannelSftp) channel;

Andy, to delete file on remote system you need to use (channelExec) of JSch and pass unix/linux commands to delete it.

Try edtFTPj/PRO, a mature, robust SFTP client library that supports connection pools and asynchronous operations. Also supports FTP and FTPS so all bases for secure file transfer are covered.

I use this SFTP API called Zehon, it's great, so easy to use with a lot of sample code. Here is the site http://www.zehon.com

Zehon seems dead. And where's the source? What 'license' is behind 'free'? – rü- Oct 06 '15 at 15:00

You also have JFileUpload with SFTP add-on (Java too): http://www.jfileupload.com/products/sftp/index.html

answered Feb 14 '09 at 11:38

JFileUpload is an applet, not a lib. License is commercial. Doesn't look active, either. – rü- Oct 06 '15 at 15:06

The best solution I've found is Paramiko. There's a Java version.
